SAN ANTONIO — They've got the superstar center, the speedy point guard and the super sub.

The San Antonio Spurs have a trio unlike any other on an NBA team.

They're three of a kind who are just two wins from another title.

Tony Parker scored 30 points, Manu Ginobili had 25 and Tim Duncan added 23 as the Spurs schooled Cleveland in championship basketball for 3 1/2 quarters, overpowering the Cavaliers, 103-92, in Game 2 last night to take a 2-0 lead in the NBA finals.

San Antonio was vastly superior in almost every way imaginable — building a 29-point lead and then relaxing in the fourth quarter — when the Cavaliers stormed back within eight points before the Spurs finally put them away for good.

"That's why sometimes I don't like to have a 20-point lead," Parker said. "I'm not going to complain. I'll take it."

The Spurs, clicking on offense and digging their sneakers in on defense, were up by 28 in the first half and were embarrassing the Cavaliers, who are in their first finals but didn't show up until it was too late.

"I think they just took their foot off the gas pedal," Cavs center Zydrunas Ilgauskas said.

The Spurs' Big 3 of Duncan, Parker and Ginobili combined for 43 points — 10 more than the Cavs — in the first half, prompting a fan to hold up a sign saying, "Bring Out LeBroom."

Following the game, Spurs fans chanted, "Sweep, Sweep."

LeBron James, limited to 14 points in his finals debut, scored 25 yesterday on 9-of-21 shooting to lead Cleveland. But he got into early foul trouble and played less than three minutes in the first quarter, sitting when the Spurs ran away to their huge lead.

Down by 25 at halftime and 27 after three, the Cavaliers, who came out flat for the second straight game, went on a 22-4 run and eventually closed to 95-87 on a three-point play by James with 4:53 left, a stunning turnaround for a team that looked done minutes earlier.

However, the Western Conference champs, who got sloppy and perhaps disinterested, responded as they almost always do. And, as usual, coach Gregg Popovich wasn't satisfied with his team's overall effort.

"Well, we played well for three quarters," he said. "But we got a win and we're thrilled with that."

Ginobili stopped Cleveland's rally by hitting a 3-pointer as he was fouled by rookie Daniel Gibson. The four-point play made it 101-89 with 2:24 remaining.

"That was a heck of a play and a heck of a shot by Manu," Cavs coach Mike Brown said. "He tricked our young fella and leaned right into him."

Gibson's 3-pointer got the Cavs within nine, but Duncan grabbed a rebound and scored inside to bail out the Spurs.

"We knew it was coming," Parker said of the Cavs' comeback. "They are an NBA team and have LeBron James. They made a big run, but in the end we made a couple of stops and got the win."
